This is a quick plug for a spiffy project that M. K. Borri (spiritplumber) has been building using my usb-fs-host object. He’s connecting an Android phone to a Propeller microcontroller, emulating the ADB debug protocol on the µC, and using this as a communication bridge in order to control robots from the phone.
This project is actually remarkably similar to the IOIO, but actually his was announced first Both projects appear to be using a single-chip solution for USB, but on the IOIO that means using a PIC that has built-in USB, whereas on this project spiritplumber used my software USB implementation for the Prop.
Currently the IOIO is a $50 commercial product, whereas this Propeller project could be built for maybe $15. It’s possible the IOIO might get cheaper once the design is opened up in the future, but for now this might be a good alternative for anyone who wants to play with an IOIO but either can’t get their hands on one, doesn’t want to pay fifty bucks for it, or who wants something that interfaces well with other Propeller objects.
He’s been getting a bit discouraged by the lack of community response, so if you’re interested at all I’d encourage you to jump in and join the discussion! His project was just featured on Hack a Day, and there’s an active discussion thread over on the Propeller forums, including links to his source code releases so far.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
